Wind turbines in the Baltic Sea are a major source of income for foreign companies. This amounts to billions of zlotys.

• The Baltic Power project, with a capacity of 1,140 MW, is a joint venture between Orlen and the Canadian group Northland Power. The project cost is estimated at approximately PLN 20 billion.
• The Baltica 2 farm, jointly developed by the PGE Group and Denmark's Ørsted, is expected to have a capacity of 1,498 MW. The investment will cost PLN 30 billion.
• The Bałtyk 2 and Bałtyk 3 projects, with a total capacity of 1,440 MW, are a joint venture between Polenergia and the Norwegian Equinor group. The combined value of both projects is approximately PLN 27 billion (excluding financing costs).

The first phase of offshore wind farm development in Poland will see projects with a total capacity of 5,900 MW. All are expected to be operational by 2030.

These projects are already underway, so they should almost certainly be built; the only possibility is delays in the implementation of some investments.

Baltic Power: 1,140 MW for nearly PLN 20 billion

Perhaps the most advanced is the Baltic Power wind farm project, which is expected to have a capacity of 1,140 MW. It is a joint venture between Orlen and the Canadian group Northland Power.

In early July 2025, Orlen announced that the first turbine in the Baltic Power project had been installed—the first turbine installed in Poland's offshore wind energy sector. The turbines were supplied by the Danish group Vestas, with a capacity of 15 MW. This investment will include 76 turbines. The farm is scheduled to be commissioned in 2026.

The cost of building the Baltic Power wind farm is estimated at approximately €4.7 billion , or approximately PLN 20 billion. A relatively small portion of this amount will go to Polish companies.

"We estimate that throughout the entire lifecycle of the farm (i.e., from development, through construction, operation and maintenance, to decommissioning), we will achieve a minimum 21% share of local content . We expect this to be the highest among projects implemented as part of the first phase of offshore wind energy development in Poland. We estimate the largest share of Polish companies in the Baltic Power value chain will be in the operation and maintenance phase, in part due to the operation of the service base in Łeba for approximately 30 years," Orlen's press team told the WNP portal.

Baltica 2: 1,498 MW for almost PLN 30 billion

The largest project in the first phase of offshore wind energy development will be the Baltica 2 farm, jointly developed by the PGE Group and Denmark's Ørsted. Its capacity is expected to reach 1,498 MW.

Baltica 2 will consist of 107 turbines with a capacity of 14 MW each, which will be supplied by the Siemens Gamesa group.

The Baltica 2 offshore wind farm is scheduled to be launched in 2027.

The cost of this investment will reach PLN 30 billion . However, the share of Polish industry in this project will not be very large.

"In the case of the Baltica 2 offshore wind farm, the share of Polish industry in its construction will meet the target of the sectoral agreement for the first offshore phase, meaning it will be in the range of 20-30 percent. Currently, the share of local content in this project is already above 20 percent. However, it should be noted that the meaningful share of Polish industry in a given project can only be achieved by measuring it throughout the entire project life cycle, i.e., also taking into account the multi-year operation phase, in which – as experience from abroad shows – domestic companies play a very significant role," the PGE Press Office replied.

Bałtyk 2 and Bałtyk 3: 1,440 MW for PLN 27 billion

The Bałtyk 2 and Bałtyk 3 offshore wind farm projects, with a total capacity of 1,440 MW, are also at an advanced stage of preparation for construction. This is a joint venture between Polenergia and the Norwegian group Equinor.

Both projects will consist of 100 wind turbines, supplied by Siemens Gamesa Group. Each turbine will have a capacity of 14.4 MW. First energy is expected to flow in 2027, with commercial operation beginning in 2028.

The combined value of both projects is approximately PLN 27 billion (excluding financing costs). Polish industry's involvement will be similar to that of other offshore wind farms.

"The process of contracting our suppliers and contractors, as well as data that will allow for a precise calculation of the share of Polish companies in the Bałtyk 2 and Bałtyk 3 projects being built by Equinor and Polenergia, is still ongoing. According to the sectoral agreement , the level of local content for projects developed in the first, pre-auction phase of the support system is to be at least 20-30% of the total project value, and we are committed to achieving this goal," the press office of the Bałtyk 2 and Bałtyk 3 projects told WNP.PL.

As assured, many Polish companies are already involved in the construction of the Bałtyk 2 and Bałtyk 3 farms, including those contracted as main suppliers, the so-called Tier 1, such as Tele-Fonika Kable and Enprom.

"Many factories in Poland produce components for our farms. There are many more examples of domestic companies, as we engage Polish contractors at every stage of project implementation, from design, through construction, to the operational phase. It is in this final phase that we anticipate the greatest share of local content, especially since it will be spread over a period of approximately 30 years," adds the press office of the Bałtyk 2 and 3 projects.

As emphasized, Equinor and Polenergia have been taking steps for many years to increase the involvement of Polish contractors in the implementation of offshore wind farms.

"Since 2019, we have been regularly organizing Supplier Days, familiarizing local companies with the specifics of these types of projects. We have established contacts with approximately 300 companies so far. We want to transfer the experience from these initial projects to the ongoing Bałtyk 1 project, where we aim to achieve local content of up to 45 percent. A successful outcome of the December offshore auction will contribute to increasing the involvement of Polish companies," says the press office of the Bałtyk 2 and Bałtyk 3 projects.

The Bałtyk 1 wind farm is expected to have a capacity of 1,560 MW and is being prepared for the so-called second phase of offshore wind farm development. Auctions for these projects are scheduled to take place in December 2025. However, there is a growing consensus in the energy community that the second phase projects will produce excessively expensive energy and should therefore not be implemented.
